Question

If n( A ) = 40, n(B) = 27 and n ( A∩ B ) = 15 what is the value of n (A U B ) ?​

Answer 1

Step-by-step explanation:

the answer will be =40+27-15

67-15=52

Answer 2

Step-by-step explanation:

n(AUB)=n(A)+n(B)-(AnB)

n(AUB)=40+27-15

n(AUB)=67-15

n(AUB)=52

Therefore,n(AUB) is equal to 52
